what is parallel-universes theory?

Question

though many people think that parallel-universes theory and m-theory are just usefull for nothing and some think it to be a interesting and realistic.I would like to know your thoughts with reason.

Answer 1

Ok, that is a fair question.



By definition, our universe is to encompass all and nothing but that we can experience, view, influence, explore, examine.

That is the important aspect, here. Something in a parallel universe cannot influence us anymore than we can influence it, parallel means "not touching at any plane".



So, there could be parallel universes, but they have no influence on us, and we do not have any influence on them. Thus, their existence can neither be proven or disproven, and that they exist cannot matter at all to our lives here, as we cannot experience them.



For this reason, speculating on parallel universe at this point in time, with our current knowledge, will achieve nothing of value, except perhaps making for some science fiction novels.

Answer 2

m-theory?

I don't have time for this i need sleep.

Anyway parallel universes exist, i don't know why i believe that, maybe i see things that are their one second and aren't the next. whether they should be or not. whether they are a different time than we are....

It's as simple as we have a left and right eye, and in that case there are at least two parallel universes that sometimes we catch glimpses of.

Go figure.... sometimes i hear things that aren't there but under different circumstances, of my life decisions they may have been. What is that...

Oh you all just think I'm crazy.. ok i can handle that!

Sometimes i daydream and yes I'm awake and my mind is out the window but sometimes my mind is next to me, that i know where i am but i have left, i am still where i am doing what i was doing but i am in another time in the same place... well similar, and there is this wave of story that I'm a part of and then all of a sudden i remember I w as just somewhere but I'm back where I was before i went "daydreaming"

I was taught all this was nonsense, and i doubt i could find someone to agree with me from my perspective but I'm probably wrong, i tend to keep this to myself. I had a crazy childhood of understanding i never knew how to get there but knew there was something there.

Hope i offered some kind of thought....

In computational complexity theory, the parallel computation thesis is a hypothesis which states that the time used by a (reasonable) parallel machine is polynomially related to the space used by a sequential machine. The parallel computation thesis was set forth by Chandra and Stockmeyer in 1976 (see References).



In other words, for a computational model which allows computations to branch and run in parallel without bound, a formal language which is decidable under the model using no more than t(n) steps for inputs of length n is decidable by a machine in the unbranching model using no more than t(n)k units of storage for some constant k. Similarly, if a machine in the unbranching model decides a language using no more than s(n) storage, a machine in the parallel model can decide the language in no more than s(n)k steps for some constant k.



The parallel computation thesis is not a rigorous formal statement, as it does not clearly define what constitutes an acceptable parallel model. A parallel machine must be sufficiently powerful to emulate the sequential machine in time polynomially related to the sequential space; compare Turing machine, non-deterministic Turing machine, and alternating Turing machine. N. Blum (1983) has introduced a model for which the thesis does not hold. However, the model allows parallel threads of computation after T(n) steps. (See Big O notation.) Parberry (1986) suggested a more "reasonable" bound would be 2O(T(n)) or , in defense of the thesis. Goldschlager (1982) has proposed a model which is sufficiently universal to emulate all "reasonable" parallel models, which adheres to the thesis. Chandra and Stockmeyer originally formalized and proved results related to the thesis for deterministic and alternating Turing machines, which is where the thesis originated.

Some of it isn't just for cool sci fi movies. Some of it is to actually explain quantum physics and the behavior of subatomic particles and why they behave as they actually do. For instance, why can a subatomic particle suddenly "exist" at one point in time and no longer "exist" at another? Where did it "go"? What did it "do"? Sure, wormholes and parallel universes and teleportation devices would be -cool-, but we need to understand a lot more about the behavior of things before we can do that.

Answer 5

in spite of if the hypothesis (no longer idea nor reality) of Parallel Universes is actual, your wondering that aims easily happen in parallel universes is unquestionably unfaithful. reason being - lots of the events (no longer all) that we see in dream are too diffused & Universally unlawful to be even remotely modern-day everywhere. as an social gathering - In a dream, I see myself going interior a Federal reserve u . s . construction yet after I enter i detect i have easily entered a large, filled, suffocating pumpkin and on suffering my way out i detect i change into interior an Apple's i-Pad easily no longer Fed construction or pumpkin. this is basically the sub-wide awake ideas playing tricks.

Answer 6

Yeah

I Think this concept do exists, As far as i have read and i believe, I know that multi universe theory states that there are many universes, As a person is doing something in one instant and doing another thing in another instant, that can simply mean that there can be two diff. universes containing these two different instants, and similarily there may be infinite different universes for infinite instances of life.....

Now practically what i observe sometimes, goes something like this:-

I am passing by a street on a bike with my friend and suddenly he talks about something, and i realised that the same instant occured sometime in back (may be a year back) i.e. i was on bike with him on the same road sometime in past and he talked abt the same thing and even i am wearing the same dress!!!!

And believe it or not it happened with me quite a some times.



So can't we take it as something multiuniverse, that i was gone back in universe of 'that instant' ! ! !

Answer 7

The main problem in Physics is an opinion that the Universe is only one.

From this opinion there are all paradoxes in physics.

Einstein and Infeld wrote:

“We have the laws, but are not aware what the body of reference system

they belong to, and all our physical construction built on sand”.

They are right.

There is no precise border now which divides two different

frames of reference:

1) System of Vacuum and

2) Gravitational frame of reference .

Now physicists, seem, do not separate these two systems,

the systems are considered common.

But it is completely different systems.

The laws of physics in Vacuum are not worked in Gravitation.

The laws of physics in Gravitation are not worked in Vacuum.



And how these two systems cooperate it is telling on this site.

Answer 8

I think that our universe is the only one universe that exist. If another universe exist, the amount of energy spread in all-universes will be unlimited, and the energy spreadness will no longer affect the activities of universes thing.
